Ok so I'm quite new to PC building and I bought a prebuild (it's custom second hand I just didn't build it myself) and I have thermaltake case fans that I'm trying to change the rgb colour of. I have downloaded the software and it says Could not find fan controller make sure fan controller is connected error H_0x0001. I have searched and it says I need to connect the usb 2.0 header but I have no idea what this is or how to do that. I have a Z390UD mobo and i9 9900k unlocked cpu. I can list any of the specs but I don't know exactly what model the case fans are or what model the case is. Please help
